Both internal and external wall cladding with clapboard is perfect solution for the owner who cares about the condition of his home. Interior decoration will create a cozy and healthy atmosphere in the room. The external one will protect the facade of the building from unnecessary damage.

In this article we will dwell in detail on why to treat the lining, what protective composition is best to do this, what is the technology for applying paints and varnishes, and also what amount should you expect when painting.

How to effectively protect a tree

How to treat the lining inside the house? This question is often asked by owners who have used wood for wood.

Today, processing lining inside the house is not a problem. You just need to choose the right protective coating that will suit a particular room.

Some are more suitable for rooms with high humidity, others perfectly protect boards from ultraviolet rays, and some generally increase the strength of wood and prevent the risk of premature abrasion.

But also an important factor in processing is that the defense should look good on the boards. It should not distort the natural structure of the tree. On the contrary, its task is to emphasize the naturalness of the material used and blend harmoniously with the rest of the interior.

Most often, the following substances are used to protect wood:

• Antiseptic
• Bio oil
• Primer

Types of varnishes for working on wood

If we talk specifically about how to treat the lining in the house, then the choice of protective mixtures is quite large.

1. Soil

This mixture is not only a complete primer, but also an excellent bio-protective agent. Primer – antiseptic is suitable for processing both indoors and outdoors.

Moreover, the use of a primer is appropriate even on an affected tree. The primer, along with a textured coating that is designed to provide protection, will extend the life of the board and keep it neat and laid.

2. Protective and decorative

One of the main qualities of the mixture is that it gives desired color wooden surface. By the way, protective and decorative coatings are an innovation in the market of paints and varnishes.

But it is very important that even when treated with such a composition, the tree structure still remains visible.

They are very convenient to use, since you do not need to use a primer first, because they already contain antiseptics. Moreover, they are resistant to fading and temperature changes.

Some types are suitable for use on damp wood. They are great for interior and exterior work.

The final coating has a soft semi-matte tone. According to the manufacturers of these products, the warranty is 8 years.

3. Scuba gear

Continuing to discuss the topic of how to treat the surface inside the house, you should definitely pay attention to the means for water based. For work inside the house, professionals recommend aqualak.

Pros of using scuba tank:

1. No smell
2. Fast interlayer drying
3. It contains no organic solvents

For external work, products with water-repellent additives are suitable, which protect wood from dirt and moisture. Of course, it is not in the budget class, but it provides the owner with durability and ease of maintenance.

4. Oils

Quite often, the surface of wood is treated with oils or their combined mixtures.

Oil coating provides protection against contamination, moisture and dust, due to the fact that it penetrates deep into the structure of the tree.

An important advantage when using varnish is also that there is no solvent aroma, but you can only smell the smell of the plant on which the oil is based. Moreover, this composition is very easily tinted, with which you can get the desired shade

Tools for painting operations

We answered the question of how to treat the lining, but there was one more question: how to treat the lining inside the house?

Its importance lies in the fact that all compositions are different in consistency, so you should pay special attention to the selection of tools so that applying the protective layer is convenient and effective.

An approximate list of what is needed when applying paint and varnish mixtures:

• Napkins
• Construction tape
• Scotch Brite
• Sandpaper (#240)
• Tray for paint or varnish
• Roller
• Brushes

Whitening

This process is the first step when painting with any composition.

It involves cleaning the boards from any contaminants.

If there are difficulties with selecting bleach, then it is best to use a special stain.

After the bleaching process is completed and the lining becomes a clean canvas, you can proceed to the second stage - priming. The third stage is applying paint.

Tools needed for whitening:

• Roller
• Tassels
• Stain (bleach)
• Solvent
• Gloves
• Eye protection glasses

We paint according to the rules

If the wooden surface has already been painted several times, then before applying a fresh layer of varnish, it is necessary to evaluate the quality.

If it is still good, then you can wipe it with a 2% soda solution.

To prepare such a solution you need 10 liters of heated water and 300 grams of soda.

After treatment with soda solution, work surface should be puttied and treated with drying oil. After such a procedure, everything wooden surfaces the house will be significantly transformed.

If painting the lining inside the house is the first time, professionals advise adhering to a certain technology in this matter in order to avoid smudges and unevenness.

Paintwork products should be applied using bristle tips. It is very important that it is thin. Otherwise a large number of paint may become unusable. To prevent the lint from leaving a mark on the walls and ceiling being treated, it is better to treat them with a soap solution before starting painting.

Particular care should be taken when applying the final layer. To ensure an even coating, it is best to start applying the protective composition from the top. Hard-to-reach places, for example, frames, baseboards, and the space near radiators, are best painted with a brush that has a diameter of no more than 5 cm.

It is best to start painting the door from the paneled side.

A dry brush will help prevent paint smudges. Upward movements of the brush will remove unnecessary imperfections from the surface.

Cost of work

The price of painting the lining for one square meter equal to approximately 280 rubles.

One square meter of the lining itself will cost the buyer approximately 320 rubles. But for the cost of the boards significant influence depends on the wood from which they are made and its grade.

Varnish for treating wood can be bought for approximately 260 rubles per liter.

We hope that this article will help every owner paint the lining with high quality, as well as choose the right materials. Good luck with your work.

Wood is one of the few finishing materials that needs processing after installation on walls and other surfaces. The most common finishing method is lining varnish, which can be used indoors and on the facade.

Types of varnishes

Any varnishes are a transparent or translucent material that is used to coat wood in order to protect it and improve its external aesthetic qualities. Before choosing what varnish to coat the lining inside the house with, you need to compare the advantages and disadvantages of all products of this type.

These materials are classified according to their composition, properties and area of ​​use. There are varnishes for interior work and external, they differ from each other in some qualities (for example, the street covering should be indelible) and smell. Where the coating is applied are divided into:

1. Parquet. Used to cover wood on floors. You can choose any color and properties (glossy, matte surface). The key difference from other products in this series is their high resistance to mechanical stress: friction, walking, etc.
2. Furniture. For finishing furniture, special compounds are used that provide long-lasting shine and unchanged color of wood over many years of use. Most of them are made on a wax basis;
3. Construction boats. They have an increased coefficient of resistance to moisture, which allows them to be used in shipbuilding. Many craftsmen use such products to decorate utility rooms (bathhouses, garages) or facades of residential buildings;
4. Decorative. The widest group. Intended solely for room decoration. This varnish can be glossy or matte. Often indelible with water and with excellent antiseptic properties. Used to cover walls in residential buildings, utility rooms(on a loggia, dacha, in a steam room, etc.), sometimes for finishing the facade.

Varnish is a coating for lining, which, depending on the main components, is not only decorative, but also protective properties. Depending on the composition they are:

1. Alkyd;
2. Acrylic;
3. Nitrovarnishes;
4. Oily;
5. Epoxy;
6. Polyurethane.

Let's look at the features of each group. Alkyd varnishes for coating wooden lining can be used on the balcony, in the corridor, living rooms. They are universal and have high resistance to external aggressive factors (high humidity, temperature changes). These paint material They penetrate deep into the wooden structure, so they take a very long time to dry - sometimes the hardening time of the coating reaches up to 3 days. Disadvantages also include the high cost of the coating and the likelihood of fire.

Colorless acrylic varnish is the most environmentally friendly option for finishing wooden panels. They preserve and prolong the natural color of the wood, while helping to protect it from fire and rot. But they have low resistance to moisture. For example, if the varnish is on acrylic base used in the bathroom or on the balcony, it can harden within 4 days. To speed up this process, it is recommended to use compositions with an increased level of crystallization.

Acrylic varnish for finishing lining is water-based (aqua) and solvent-based. Aqualak (Tikkurila, Pinotex, Poly R and others) has a wider range of uses due to the fact that it does not deform the wood. At the same time, the solvent is more resistant to irritating factors and can even be used to cover the floor.

Transparent nitro varnish has no pronounced odor and dries very quickly; at the same time, its price is almost two times lower than options with an acrylic or alkyd base. It is used for painting eurolining inside and outside the house, but it has a significant drawback. The product contains toxic substances that can cause poisoning. After the mixture dries, they are harmless, but it is not recommended to heat walls with such a coating, and it can only be applied while wearing a protective mask.

Oil varnishes are also called impregnation. They are rarely used independently; they provide primary wood processing. Depending on the oil and resin in the composition, the coating may have different colors: Light brown to dark chocolate. After hardening, they form a hard film on the wall or ceiling that is easy to clean. Further processing is carried out on top of it. Among the advantages: moisture resistance, protection of wood from exposure to UV rays, extension of the durability of the coating. The disadvantages include high level fire hazard.

Epoxy varnish can be used to paint walls, ceilings, floors, furniture and other surfaces. It has excellent properties of strength and resistance to high humidity. Thanks to this versatility, it is very popular among professional and home craftsmen. You can choose any colors, it is easy to use and apply, and is very flexible. Among the disadvantages is the relatively high price of the coating - from 3 dollars per square meter (at optimal consumption).

Polyurethane matte and glossy varnish is the most popular and affordable option of all of the above. It contains synthetic fibers that make the mixture easy to apply and increase the durability of the wood. Depending on your needs, you can choose a varnish like paint to change the shade of the wood, or use a transparent option. It comes in white, brown, dark red, etc.

Application

To renew the wall covering, you need not only to know how to remove varnish from the lining, but also how to use the coatings correctly. To begin with, the walls (floors, ceilings) are washed; for this, take a damp cloth with special cleaners for wood. This is necessary to remove dust and dirt from the wood pores.

Next, it is removed old layer coating (if there is one) or the lining is sanded. For this purpose they are used as special grinding machines, and low abrasive sandpaper and metal brushes. This is necessary to level the surface and eliminate nicks. After this, you need to paint the wood with drying oil. It can be bought at any hardware store. The drying oil will fill microcracks in the lining and help improve adhesion; after the drying oil has dried, a primer is applied to the walls.

How to paint lining with varnish:

1. Movements should go along the tree structure, preferably from top to bottom. The first layer is made dense, but without streaks;
2. For painting, you can use both brushes and rollers, but it is more convenient to work with brushes. The material of the working part of the instrument must be made of natural wool;
3. Experts recommend doing 3 layers of varnish, the last being the thinnest. It is leveling. Afterwards the room is left to dry and ventilate. Once every 3 years, the coating will need to be renewed to avoid cracks and chips.

You can buy varnish for lining at any hardware store; on average, the price varies from $6 per can. The cost may vary depending on the brand and purpose of the product.

For many craftsmen completing interior wall cladding with wood, or starting to repair such cladding. You have to choose - what is the best way to cover the lining inside the house?

And, despite what is available on the market today widest choice protective and decorative materials for wood, choosing the right composition can sometimes be very difficult.

Protection and durability of the lining

Principles for selecting a protective composition

When choosing what to cover the lining inside the house with, we must first answer three questions:

• Does wood siding need to be coated at all – or can it be left uncoated?
• In what room will we cover the wood paneling - wet or dry?
• Is it necessary to tint the lining, or is it necessary to preserve the natural color of the wood as long as possible?

It is based on the answers to these questions that we will select materials for impregnation and coating of the surface of the lining indoors.

Note!
In this article, we are not considering how to cover the lining outside the house.
The whole point is that external cladding completely different requirements are put forward, which means that the composition for processing the lining must be fundamentally different.

Lining without coating

The very first option that should be considered is lining without any coating at all. And in principle, such a solution, despite its apparent impracticality, has its reasons.

The point here is this: the wooden paneling of the room, left without protective coating, darkens over time, and this happens quite quickly. And here your own taste comes into play - if the darkened wood suits you, from an aesthetic point of view, then spend money on additional processing not worth it.

Advice!
Not so long ago, a popular way of processing lining was to artificial aging by using blowtorch. After several passes, the lining not only darkened (as in the photo), but also released resin, which gave it an interesting appearance.

Another aspect is purely practical. Finding a high-quality and effective coating for sauna lining is quite difficult, and it is quite expensive.

That is why many decide not to waste time and money, but simply periodically change the lining - for example, once every five to seven years. If you use inexpensive wood cladding and install it yourself, then this option has a right to exist.

Covering functions for lining

Well, what if we decide to choose the most suitable covering for lining inside the house, then it is necessary to understand what functions these coatings can perform.

For the interior cladding of a clapboard house you need:

• Ignition protection. It is achieved by treating wooden panels with fire retardants – substances that significantly reduce the flammability of wood.
• Rot protection. Antiseptic treatment is very important, especially where the lining comes into contact with moisture.
  For example, when you choose what to cover the lining of a loggia with, be sure to include an antiseptic composition in your purchase list.
• Protection against mechanical damage. Although it is primarily the wooden floor that needs to be protected from chips and scratches, additional strengthening of the wall cladding will also not hurt.
• UV fade protection. The more effective this protection is, the slower the wood changes its original color.
• In addition, the outer covering of the tree should provide it with an attractive appearance.- and this means that we can either give the lining the shade we need using tinting, or simply apply a transparent varnish with a matte, semi-matte or glossy surface.

Typically for processing wood paneling Several compounds are used simultaneously inside the house (see). This is due to the fact that it is almost impossible to combine all the functions in one product.

Compositions for processing lining

Impregnations and stains

When choosing whether it is better to cover eurolining or regular lining, we need to consider different types compositions. And first of all, we will look at substances that penetrate into the wood itself - impregnations and wood stains.

• Drying oil- an option that is hopelessly outdated and is used today exclusively for processing utility premises.
  It does a good job of protecting wood, but within a few years after application it becomes dark and the impregnated wood becomes covered with a sticky film.
• Protective impregnations– used to impart antiseptic and fire-fighting properties to the lining. As a rule, protective impregnations are applied to a wooden panel on both sides, so the application must be done before installation.

Note!
As a rule, the instructions for protective impregnation contain information about its compatibility with various finishing coatings (varnishes, paints, etc.)

• Antiseptic film coatings - similar in purpose antiseptic impregnations. Quite rarely they are used inside the house, but if you are looking for something to cover the lining outside, then antiseptic coatings are exactly what you need!
• Stains are used to give wood color and also to disinfect it. They are used in the same way as impregnations.

The most popular manufacturers of impregnations and stains for lining are “Tikkurila”, “Senezh”, “Pinotex”, etc. We recommend choosing compositions for wood processing from trusted manufacturers - even if their price is slightly higher, the quality is guaranteed not to disappoint!

Varnishes and paints

As a rule, after treating the lining with penetrating compounds, it looks somewhat unpresentable.

That is why, in addition to staining or impregnation, the lining is opened with a protective varnish with decorative properties, or paint.

• Varnishes are used if we want to preserve the natural color of the lining and texture natural wood. For interior decoration best suited - they are non-toxic, fireproof and easy to apply.
  The texture of the varnish can be either matte or glossy.
• If you are looking for something to cover the lining to prevent it from darkening, choose a transparent varnish with high UV resistance. But if you want to “age” a light lining a little, give it a darker shade, then it is better to open it with varnish with tinting additives.
• Alkyd varnishes are highly durable, which is why they are most often used to treat floorboards or parquet. The lining should be coated with alkyd varnish only in those places where it experiences mechanical stress.
• Paint for lining is used less often than varnish - but, nevertheless, it is used. The best solution is a translucent paint that partially preserves the wood texture. The most common brands of paint for lining are “Belinka”, “Texturol”, “Senezh”.
• Wax paints are the best, but at the same time, the most expensive and difficult to work coating for lining inside a house. The basis of such paints is most often natural linseed oil.

Note! How they cover the lining in saunas and baths is a separate question! For these purposes, it is best to use specialized compounds such as “Supi saunasuoja” or “Evrotex-Sauna”.

Lining coating technology

Preparation for coating

Covering the lining with protective and decorative compositions is done in the following sequence:

• We carry out the initial processing of the lining: dry it, clean the surface with a brush-scraper, and then sand it, sanding it minor irregularities. In the same way, sanding must be carried out before renewing the lining that was previously varnished.
• If there are darkened areas on the surface of the wooden cladding, we deep clean the lining using wood bleaches (Senezh Neo, Frost, etc.).

• After bleaching, rinse the paneling thoroughly with water and dry it again.
• To fill the pores in the wood, we treat the panels with a primer. The primer improves the adhesion of the lining to the varnish and reduces its consumption.
• After applying the primer, we impregnate the wood with antiseptics and fire retardants. You can also use compounds that provide comprehensive protection for wood.

After the lining, treated with primer and impregnation, has completely dried, you can begin painting or varnishing it.

Applying varnish to clapboard sheathing

We apply varnishes and paints to wooden panels using brushes or sprayers (depending on the material and area of ​​the surface being treated). You can study the application technology in detail by carefully watching the video instructions included with the article.

Processing is carried out according to the following scheme:

• To apply the varnish, use a brush with natural bristles.
• Mix the water-based varnish with the tinting thoroughly - otherwise the tinting of the lining will be uneven.
• On the wall covered with clapboard, apply the first layer of varnish, moving the brush along the grain of the wood.
• Leave the applied layer until completely dry. After the varnish has completely dried, sand it and proceed to applying the next layer.

• If we plan to cover the eurolining with tinted varnish, then each subsequent layer of varnish should contain less tinting pigment than the previous one. This gives the varnished surface depth and an attractive shine.
• Make the last layer of varnish transparent and do not sand it after application.

Now you know how to cover the lining in your house, and most importantly, you know how to do it! Therefore, if you are faced with such a task, you will be able to cope with it yourself, saving both time and money!

To protect the interior upholstery of a house made from lining, you should use various compositions. Often, in order to protect against mechanical and other damage and moisture, they use varnish on the lining, which will extend the life of the panels, improving their appearance. The advantage of such a coating is that the composition can be selected according to the appropriate shade, which will allow it to convey a certain depth of coverage and shine.

Protection procedure

Usually for upholstery interior walls panels of their coniferous and hardwood that are subject to the aging process. Even if the type of wood was chosen, depending on the load planned for the room. However, such an undesirable aging process can be significantly slowed down.

Speaking about the list of negative factors that have a detrimental effect on the lining, the following should be highlighted:

• FACTOR 1: Increased exposure to sunlight.
• FACTOR 2: High humidity air, contact of wood with water is especially detrimental.
• FACTOR 3: Pest beetles.
• FACTOR 4: Mechanical damage.
• FACTOR 5: Growth of microorganisms on the surface of the lining.

With help various types impregnations and compositions, you can achieve the appearance of a protective layer that will protect the wood from negative influence environment. These include temperature changes, mechanical influences, increased moisture formation, etc.

Application of water-based varnishes

Features of such compositions

Most often, compounds such as lining varnishes, which are usually used indoors, are used to protect wood.

Aqueous compositions used for processing the internal cladding of lining are made on an acrylic base, as well as on a polyurethane base.

According to their composition they are divided into:

• Consisting of one component. They are characterized by minimal strength, do not last too long, but are easy to handle;
• Consisting of two components. These components are the base and hardener. This composition is positioned as a varnish for eurolining, since its protection is maximum.

The coatings do not contain a solvent, which allows them to be considered highly environmentally friendly products. As for the composition consumption and how to varnish the lining, it depends on the brand, as well as on the thickness with which it is applied.

Below are approximate calculations quantities:

• For planed wood- approximately 1 kg of varnish per 16 square meters;
• For sawn wood - approximately 1 kilogram of composition per 6 square meters.

The positive aspects of water-based varnishes

Speaking about water-based varnishes for wooden lining, they should be highlighted positive sides:

• PLUS 1: Safety from a fire point of view, since the water base is not capable of supporting combustion.
• PLUS 2: Highly environmentally friendly. This is due to the absence of any toxic substances in the composition. This allows them to be used indoors without harm to health.
• PLUS 3: Easy to use. The instructions from the manufacturer will help. Moreover, you can do this with your own hands, without resorting to the help of specialists.
• PLUS 4: Resistance to appearance yellow color subject to exposure to ultraviolet rays on the coating.

An additional advantage of this varnish is big square transfer. This is especially important if the application is by spraying, as nothing will be left inside the spray equipment.

Negative sides

When choosing which varnish is best for lining, study not only the pros, but also the disadvantages of this type of coating. also requires a balanced approach.

Important disadvantages include:

• MINUS 1: Long wait for drying (up to a day).
• MINUS 2: The price is high.
• MINUS 3: At the point of drying, humidity and temperature changes have an effect;
• MINUS 4: When storing the composition, pay attention to the storage conditions: do not freeze.

It is important! In principle, if the varnish is expensive and of high quality, it can be frozen or thawed several times. However, it is better to do without experiments.

In fact, water-based varnish for wooden lining is one of the most good options. After all, the shortcomings described above are not fatal.

How to apply water-based varnish

Preparation process

The panels must first be prepared for painting.

Accordingly, before covering the lining, we:

• STEP 1: We carry out the process of cleaning the lining from dust; it is necessary that there is no dirt, fungal formations, or other types of microorganisms on the surface of the lining.
• STEP 2: We sand the walls of the room, you can use simple sandpaper. It is not at all necessary to use grinding machines. Sanding is necessary in order to achieve a perfect finish. flat surface, application finishing coating which will give a mirror shine effect.

If you want to get the effect of a mirror surface (similar to the photo), you should use the so-called wet grinding, before which the lining must be moistened and allowed to dry after processing.

• STEP 3: Before applying varnish, the surface should be treated with a primer, this will reduce the consumption of too expensive material. Apply varnish only after the primer has dried.

Carrying out varnishing with aqueous composition

You can apply clapboard varnish inside the house using a roller, brush, sprayer or swab, depending on the availability of places. Accordingly, the less accessible the space, the smaller the brush is needed so as not to go beyond the edges to be painted. Applying varnish with a brush

• TIP 4: In order to add depth to the surface, the lining should first be treated with a dark-colored varnish, and then with a transparent one, to which 5 to 10% tinting can be added.
• TIP 5: Several are preferable thin layers than one thick one.

In conclusion

Now you know which varnish for lining is better. Pay attention to the tips given in this article. The use of water-based varnishes is very convenient option coatings for wooden panels.

Artificial Decoration Materials gradually experienced their boom, and gradually wood began to win back the market. This statement is relevant not only for the construction of houses, but also for their interior design clapboard. Completely environmentally friendly cladding adds additional comfort, warmth and beauty to the premises. However, not knowing how to cover the lining, some owners leave it unprotected. As a result, beautiful wood, which with proper treatment could last for many years, needs to be replaced after 5-7 years. This happens due to its destruction, chipping, stains during cleaning, and contamination.

Varnishing of lining

Main purpose of wood processing

After covering interior spaces clapboard, it is necessary to carry out the first surface treatment no later than a week later. By using a varnish that is correctly selected for the conditions of the internal microclimate, you will be able to guarantee the material:

• durability - after treatment with varnish, the appearance of fungus, mold, and rotting processes is no longer possible;
• aesthetics – neutral reaction to UV radiation;
• improved performance – the outer layer protects against impacts and other types of physical impact;
• fire resistance – protected wood can withstand strong flame pressure.

Regardless of the type of varnish chosen, the lining is pre-treated various materials: drying oil, antiseptic, protective impregnation, stain or heat treatment. For self-execution This procedure uses a torch to slowly scorch upper layer each element, achieving uniform darkening.

During processing, especially coniferous species, resin is released, which gives the lining a special originality. However, now such operations are carried out much less frequently, since more effective ones are available on sale. protective equipment and varnishes, which work much faster.

How to choose a varnish

When choosing what to cover the lining with, you need to familiarize yourself with all types of similar products. The most popular varnishes among builders are:

• water soluble;
• polyurethane;
• alkyd;
• acrylic.

All of them are suitable for application inside residential premises, as they do not emit toxic fumes and are completely safe for the health of the inhabitants of the house. At the same time, polyurethane and alkyd types of varnishes can also be used for external treatment of structures, which makes them universal and facilitates the task of painting for owners.

This is what varnished lining looks like

Acrylic

They perfectly help wood retain its unique texture and are good choice for those who are just deciding how to paint the lining inside the house. They protect surfaces from exposure to sunlight, and the aesthetic perception of the lining only benefits from this.

Depending on the main composition, following the instructions, acrylic coatings diluted with water, alcohol or ethers, which dry very quickly after application. Acrylic surfaces do not tolerate moisture well, so when dirty spots on the walls, it is better to refrain from the desire to wash them. It is especially undesirable to use these materials in particularly wet areas, for example, in the kitchen.

Alkyd

They are no less beneficial, because they are moisture resistant and, unlike their acrylic counterparts, the surfaces coated with them can even be washed. True, without using household chemicals and abrasives. An actual advantage if small children and pets live in the house. In addition, after complete drying, the varnish becomes so durable that it can withstand some physical exercise, protecting the wood directly from chips and scratches.

The disadvantage of alkyd varnishes is the unpleasant odor when working with it and the long drying time, which takes at least 48 hours. The last problem can be easily dealt with by adding a special hardener to the composition.

Polyurethane

Their advantages are difficult to overestimate, since this type of varnish protects the lining not only from problems and aging during interior lining, but climatic tests on external walls designs. This coverage guarantees:

• increased moisture resistance;
• lack of reaction to chemical components, alkalis;
• UV resistance.

Having so many positive qualities determined the price of polyurethane varnish– it is significantly higher than other analogues.

Water soluble

All water-based varnishes, including acrylic, are characterized by quick drying and complete absence of unpleasant odors. They are so non-toxic that you can paint the lining inside a house using such compounds even without a respirator. Water-soluble varnishes are applied only to the lining located inside the house.

Example of water-soluble varnish for lining

What to consider additionally

There are several nuances, taking into account which you can create a very durable, high-quality and aesthetic coating:

1. Regardless of the type of varnish chosen, maximum strength can be achieved by applying it in 2 layers.
2. If the varnish is available for sale in two forms: translucent and completely transparent, apply the second option first. The surface will receive a certain, more saturated shade, but at the same time the structure of the wood will be preserved for visual inspection.
3. We must not forget about the protective impregnation against biocorrosion, which must be carefully treated with the lining before varnishing.
4. During operation, the varnishing agent is often stirred to maintain a uniform structure. When the first layer is completely dry, you need to sand it a little and only then re-paint the lining inside the house.

Coating the lining with varnishes does not present any particular difficulties. The owner of the house can cope with such work himself. Especially if it uses the information provided.
